How to use set method of a different class in java? -

how can set value of parameter of class a in class b using setvara method of class a?

public class a{  string vara; public string getvara() {         return vara;     } public void setvara(string vara) {         this.vara=vara;     } }  public class b{  string name = "abc"; obja = new a(); obja.setvara(name) ; ## lines throws error  } 

the error is:

syntax error on token "name", variabledeclaratorid expected after token , syntax error on token(s), misplaced constructs 

public class a{      string vara;     public string getvara() {         return vara;     }     public void setvara(string vara) {         this.vara=vara;     } }  class b {     string name = "abc";     obja = new a();      b() {         obja.setvara(name);     } }
